Its real-time monitoring capabilities, paired with automatic calibration and robust protection, make it suitable for stack and furnace exhaust monitoring, complying with CPCB and US EPA standards for environmental safety.

Reliable Design & Flexible Installation

Constructed with a powder-coated mild steel enclosure and rated IP65 for weatherproof performance, the monitor offers natural air cooling and operates quietly under 55 dB(A). Flexible mounting options, including flange and bracket, cater to various installation requirements. Its LCD/digital display ensures clear visibility of readings and system status.

FAQ's of Dust Opacity Monitor:

Q: How does the Dust Opacity Monitor measure dust concentration in stack emissions?

A: The monitor uses an optical transceiver (LED/photodiode) system to transmit an infrared laser beam through the gas stream. The amount of light obscured by dust particles is detected and converted into an opacity percentage, providing real-time insights on dust concentrations in compliance with industry standards.

Q: What benefits does automatic zero and span calibration provide?

A: Automatic zero and span calibration ensures that the monitor consistently delivers precise and drift-free readings without manual intervention. This feature minimizes maintenance, reduces operator workload, and guarantees high measurement accuracy over time.

Q: When and where should this Dust Opacity Monitor typically be installed?

A: This instrument is ideally installed on industrial stacks or exhaust outlets associated with processes such as furnace emissions or scrubber bypass monitoring. It can be wall or stack mounted, using flange or bracket arrangements, and is suitable for continuous operation in environments ranging from ambient to 250C with up to 95% RH (non-condensing).

Q: What communication and alarm interfaces does the monitor support?

A: The monitor offers multiple output options including 4-20 mA analog signal, RS-485 MODBUS (also RS-232), and digital alarm outputs. It features both visual and audible alarms that activate when dust opacity exceeds preset thresholds, ensuring timely notification and response.

Q: How is lens maintenance handled on this monitor?

A: An optional instrument air window purge can be integrated to continuously clean the lens and prevent dust accumulation, helping maintain measurement accuracy and reducing manual cleaning needs.

Q: What are the primary applications of this Dust Opacity Monitor?

A: Common applications include continuous emission monitoring in industrial stacks, furnace exhaust, and other high-temperature gas discharge points where regulatory compliance and process optimization are vital.
